This paper presents a fault-tolerance technique for H.264's Context-Adaptive Variable Length Coding (CAVLC) on unreliable computing hardware. The application-specific knowledge is leveraged at both algorithm and architecture levels to protect the CAVLC process (especially context adaptation and coding tables) in a reliable yet power-efficient manner. Specifically, the statistical analysis of coding...
This paper presents an application-driven algorithm for Dynamic Thermal Management (DTM) for the High Efficiency Video Coding (HEVC). For efficient design of such a DTM policy, we perform an offline thermal analysis of an HEVC encoder and demonstrate the impact of different video sequences and different coding configurations on the processor temperature. Our thermal analysis is leveraged to develop...
We present a novel content-driven memory pressure balancing and video memory power management scheme for parallel High Efficiency Video Coding (HEVC). The key is to leverage the application-specific knowledge to balance the (instant) access pressure on Scratchpad-based Video Memories (SVMs) for parallelized video processing. Our scheme accurately predicts the memory requirements of each processing...
